The sketch shows how a neat window conservatory may be made at
small cost that can be fastened on the house just covering a
window, which will provide a fine place for the plants. The frame
(Fig. 2) is made of about 2 by 2-in. material framed together as
shown in Fig. 3. This frame should be made with the three openings
of such a size that a four-paned sash, such as used for a storm
window, will fit nicely in them. If the four vertical pieces that
are shown in Fig. 2 are dressed to the right angle, then it will
be easy to put on the finishing corner boards that hold the sash.

The top, as well as the bottom, is constructed with two small
pieces like the rafters, on which is nailed the sheathing boards
and then the shingles on top and the finishing boards on the
bottom.
** How to Make an Electroscope [103]
An electroscope for detecting electrified bodies may be made out
of a piece of note paper, a cork and a needle. Push the needle
into the cork, and cut the paper in the shape of a small arrow.
Balance the arrow on the needle
[Illustration: Simple Electroscope]
as shown in the sketch, and the instrument will then be complete.
